js-data

Inspired by Ember Data, js-data is the model layer you've been craving. It consists of a convenient framework-agnostic, in-memory cache for managing your data, which users adapters to communicate with various persistence layers.

You can use the http adapter, which is perfect for communicating with your RESTful backend. You could also use the localStorage adapter. More adapters are coming, and you're free to implement your own.

Unlike Backbone and Ember Models, js-data does not require the use of getters and setters, and doesn't wrap your data with custom classes if you don't want it to. js-data's internal dirty-checking (via observe-js or Object.observe in supporting browsers) allows for powerful use cases and an easy avenue for implementing your own 3-way data-binding.

Supporting relations, computed properties, model lifecycle control and a slew of other features, js-data is the tool for giving your data the respect it deserves.

Latest Release: 0.4.2

js-data is pre-alpha. The API is subject to change, though the current api is well tested.

If you want to use js-data, keep a close eye on the changelog. 1.0.0 will introduce strict semver (until then, minor number is bumped for breaking changes).

Supported Platforms

Browsers: Chrome, Firefox, IE 8+, Safari, Opera, iOS Safari 7.1+, Android Browser 2.3+

Node: 0.10+ (at least)

Quick Start

bower install --save js-data js-data-http or npm install --save js-data js-data-http.

Load js-data-http.js after js-data.js.

var store = new JSData.DS();

// register and use http by default for async operations
store.registerAdapter('http', new DSHttpAdapter(), { default: true });

// simplest model definition
var User = store.defineResource('user');

User.find(1).then(function (user) {
  user; // { id: 1, name: 'John' }
});

All your data are belong to you...
